地震作用下土工合成材料加筋土边坡动力分析
Dynamic analysis of geosynthetic reinforced soil slope under seis mic action
摘要
Abstract
A dynamic numerical simulation model of geosynthetic reinforced soil slope was established by virtue of finite difference method.Based on this,horizontal displacement,deformation and potential sliding surface of geosynthetic reinforced soil slope and coupling characteristics between geosynthetic and soil were analyzed.It is shown that,under the seismic action ,the horizontal displacement and the deformation of the reinforced soil slope are smaller than those of soil slope without reinforcement.The shear strain increment of the geosynthetic re-inforced soil slope is smaller than that of the soil slope without reinforcement,therefore the possibility of the slope sliding along the potential sliding surface of geosynthetic reinforced soil slope is smaller.The geosynthetic ele-ments near the slope toe bear larger coupling stress.The results are helpful to the seismic design of the geosyn-thetic reinforced soil slope.关键词
